US President Donald Trump announced that White House Deputy Chief of Staff Stephen Miller will replace Susie Wiles as chief of staff, effective Monday.
The announcement marks the most senior dismissal in the administration since Republicans suffered a crushing defeat in the midterm elections three days earlier, losing control of both the House of Representatives and the Senate.
It is also one of the most significant dismissals of Trump's second term, alongside the removal of National Security Adviser Mike Waltz in 2025 and Attorney General Pam Bondi in April 2026.
